Y., A CORPORATION OF DELAWARE ELECTRICAL connnns m Application filed January 14,4925. Serial No. 2,384.

This invention relates to'electrical devices, and more particularly to condensers in which the dlelectric is a vacuum.

The object of this invention is to vide a condenser inv which the dielectric losses are eliminated to a great extent, but the proper cooling becomes important, and

I it is to take care of this feature that I produce a condenser which is extremely simple in constructiomdurable and eflicient.

Another object of this invention is the production of a vacuum condenser consistmg of an outer and an inner electrode, the outer electrode being so designed as to roduce or offer the maximum cooling sur ace. A further object of this invention is the production of a vacuum condenser comprismg an outer and an inner electrode, the inner electrode being su ported within the outer electrode in' a nove yet rigid and durable manneri."

. A still further object of this invention is the production of a vacuum condenser comprismg an outer electrode consisting of a metal container capable of being cooled either by air, water or oil ,inany suitable or well known manner, and being adapted to sup ort within itself, through the medium of a glass hood, an innerelectrode comprising a c lindrical metallic section with a contracte neck or sleeve portion which engages and is secured to a tubular core tages of this invention.

formed in the center ofthe hood and integral therewith.

With these objects in view, and such others as may hereinafter a pear, it is to be clearly understood that whi e I have shown certain component and co-operative parts which I deem essential to carryout the fundamental principles involved, I do not limit myself to the exact details of construction so illustrated and described since it is obviouscthat many and various minor chan es ma be resorted thereto without sacri cing t e spirit or any of the advan- In the drawings forming a partof this specification,

represents an electrode consisting of a 1101- low shell or container, preferably cylindrical in form, and'constructed of iron or any other suitable metal, having a flange 2 at its open end provided with a series of apertures 3 therein, the object of which will hereinafter appear.

This shell or container, which will be hereafter referred to as an outer electrode, is provided with a-series of heat radiating flanges 4 formedintegral with the outer wall of the electrode and extending at right angles therefrom, though it is obvious that they may be otherwise formed and will produce equally as good results. These heat radiating flanges are adaptable for cooling the electrode by means of air, yet it isobvious that water or oil may be employed, and that any cooling means may be used.

Mounted upon the flange 2 of the outer electrode 1 is a cylindrical section 5 having a flange 6, alike in formation to the flange 2, and provided with 'a series of apertures 7 so placed as to register with the apertures 3, for the reception of bolts 8 provided with nuts 9 by means of which the cylindrical section 5 is secured in lace, there being interposed between the anges '2 and 6 a suitable gasket 10, ,or the,.parts may be cemented together. bolts 8 and nuts 9 may act as avterminal for the outer electrode and provides adequate means for securingor attaching a lead 11, the free end of which may be secured beneath the nut.

The cylindrical section 5 is formed with an offset or flange 12 supporting a smaller cylindrical section 13 formed integral therewith and in such a manner as to produce a channel 14 between the inner wall of they Either or any one of the shape so as to produce the greatest degree of strength, is formed with a central tubular core 16 projecting through the wall of the hood, as at 17, so as to lend additional strength in supporting the terminal 18, which is provided on its free end with nuts 19 between which a lead 20 is secured. This terminal which fits snugly in the tubular core 16 effectually seals the same, and at the same time imparts strength and rigidity thereto.

Mounted upon the inner end of the core 16 is a sleeve 21, formed integral with an .inner electrode 23, which is cylindrical in form and is supported or suspended by the sleeve centrally within the outer electrode 1 in such a manner that the inner wall of the outer electrode and the outer wall of the inner electrode will be substantially parallel to each other and evenly spaced.

The sleeve 21, which is integral with the inner electrode, is connected by suitable conductors 24 to the terminal 18. The sleeve, which is cemented or shrunk upon the tubular core 16, binds between itself and the terminal 18 a small portion of the tubular core and thereby gives rigidity and strength to the structure.

While I have shown and described the preferred embodiment of my invention, I wish it to be understood that I do not confine myself to the precise details of construction herein set forth, by way of illustration, as it is apparent that many changes and variations may be made therein, by those skilled in the art, without departing from the spirit of the invention, or exceeding the scope of the appended claims.

The parts 1, 5 and 23 will of course be of any material suitable for my purpose.

Having thus described the various features of my invention, what I claim as new and desire to secure by Letters Patent'is:

1. A condenser having a conductive casing, an insulating hood attached thereto, a vertical tubular core integral with the hood, a terminal mounted in the core, an electrode mounted on the core, and means for connecting the terminal and electrode.

2. A condenser comprising a conductive tubular flanged section, an insulating hood sealed upon said section, a vertical tubular' core integral with said hood, a cylindrical electrode mounted upon said core, a terminal mounted in said core, and means for connecting said electrode and terminal.

3. A condenser having a casing, an insulating hood forming parts of said casing, a vertical tubular core integral with the hood, a terminal mounted in the core, a sleeve telescoping a section of the core and terminal therein, an electrode supported by the sleeve, and means for electrically connecting the terminal and electrode.

4. In a condenser casing, a tubular seotion having an external and an internal flange, a smaller tubular section integral with the internal flange whereby a channel is formed by the tubular sections and flange connecting the same, a hood having a curved surface telescoping the smaller tubular section, and resting in the channel.

5. A condenser having an electrode comprising a shell with integral external means for cooling, an insulating hood for said shell, a core insaid hood, and an electrode suspended by the core within the shell, said shell and hood being adapted to maintain a vacuum betweenthe electrodes.

6. A condenser having two electrodes, one of which surrounds the other, radiating means for cooling the outer electrode, means for completing an enclosure of said outer electrode, said means supporting the inner electrode, the outer electrode and said means being adapted to maintain a vacuum between the electrodes.
